BTI - with integrated bridge breaker

Really well mixed

When media are inclined to bridging, smooth product delivery to the conveying elements cannot always be assured. The BTI hopper pumps from SEEPEX provides a solution. The rectangular hopper contains two counter-running paddle shafts equipped with their own drive system. These mix highly viscous media so thoroughly that bridging cannot even begin to take place - ensuring optimal delivery of the medium to the pump at all times.

Features and Benefits

No bridging

Thanks to the bridge breaker consisting of two counter-rotating paddle shafts, which keep the medium in constant motion

Optimum product conveyance

Feed flow to the screw conveyor is guaranteed, even for highly viscous products, thanks to bridge breaker

Flexible control

Flexible adjustment of speed thanks to separate drive system for bridge breaker - irrespective of pump speed

Easy maintenance

Quick and simple maintenance thanks to the easy dismantling of the compression casing

Technologies, accessories and options

Dry running protection / TSE

TSE monitors the temperature of the rotating stator and shuts down the pump when the limit value is reached to protect the pump from dry running.

Retensioning device

With this device, a worn stator can be evenly readjusted at several points so that the clamping between the rotor and stator is once again optimal and the pump performance increases.

Overpressure Protection

The pressure gauge switches off the pump as soon as a pre-set pressure is exceeded or not reached and protects the pump from increased wear and tear or piping damage.

Standard base plate

Short base plate B with geared motor for all standard applications.

Standard gland packing

Universal seal for hopper and standard pumps for sealing the plug-in shaft and suction casing or feed hopper. Also available with grease or lantern ring to shut off the media flow. Can also be supplied with upstream labyrinth seal and additional flush connection or lubricating device.

Single-acting mechanical seal

Universal standard mechanical seal for dosing, food applications and semi-submersible pumps for sealing the plug-in shaft in the suction casing or the hopper.

Cartridge mechanical seal

Ready-to-install pre-assembled units with supply connections and attachment brackets for quick replacement.

Universal joint sleeve protection

Stainless steel protective housing protects the universal joint sleeve from mechanical destruction by rough parts made of plastic, metal, wood, etc. Up to 10,000 operating hours guaranteed.

Pressure Branch

With gauge connection. Flange connections alternatively to DIN or ANSI.


Wear resistant and corrosion-proof materials.


For connection of pump and drive and to secure the assembly to the base plate or directly to the foundation.


Geared motors, variable speed drives or frequency controlled motors of all major manufacturers, directly flanged to the pump without additional couplings or guards. Covers made of stainless steel are available.

Compression casing

Conical casing ensures optimal feeding of the medium into the conveying elements. Optional sliding compression casing for quick and easy maintenance.


The seal on both ends is moulded as an integral part of the elastomeric stator; corrosion of the stator tube is never a problem because the pumped liquid never comes into contact with the metal tube or the bonding adhesive. Available with optional adjustable stator retensioning device.

Separate Drive

For bridgebreaker, which can be operated with different speed than the pump.

Bridgebreaker device

Integrated bridge breaker device with two counter-rotating paddel shafts to mix for very viscous media tending to build bridges.

Full screw

Auger feed screw reduces backflow of medium, ensuring optimized filling of the pump cavities.
